Thank you wolram for that link.

His basic conjecture is,
He uses Einstein and Lemaitre's comments to builds his case, which may be now a little outdated.

I also found it a bit confusing as later he says,
So is he suggesting DM or DE as 'Mach's ether", or both?

Personally I would have taken the Brans Dicke route and suggested that their scalar field might be called 'Mach's ether' and is the same as DE, and possibly the QCD vacuum, rather than the same as DM. But then you would have to find a way of having a massive enough scalar field without it perturbing solar system GR experiments........
